Abstract

Nannochloropsis sp., an unicellular marine microalgae, has potential function as a food source for fish larvae and in chemical industry. Microenvironmental conditions, especially nitrogen and salinity stress in marine ecosystems, became major factor affecting the growth of Nannochloropsis sp.The aim of the experiment was to study effect of different salinities and nitrogen dosages to the growth and lipid contents of Nannochloropsis sp. cells.The experiment was arranged in factorial with three replicates. The first factor was salinity (28 ppt and 38 ppt), and the second factor was nitrogen dosage (100% and 50%). Results of the experiments indicated that nitrogen starvation and high saline concentration affected cell density of Nannochloropsis sp. in different level. The results showed that combination treatments of nitrogen starvation and salinity reduced cell density (treatmant A, B, and D), except in treatment C. Combination of high salinity and high N dosages resulted ini steady growth of Nannochloropsis sp. These results suggest that Nannochloropsis sp. are able to overcome salinity stress (38 ppt) in the presence of optimum concentration of nitrogen in the growth cultures.The results also shows that there were no significant differences of crude lipid content between treatments and no correlation between population density and crude lipid content. These results suggest that no simple correlation between population density and crude lipid concentration. On the other hand, population density was not the only factor affected crude lipid concentration in the microalgae cell.Keyword: Nannochloropsis, population, crude lipid

Abstract

The aims of this research was to determine the immunogenicity of inactivated vaccine A. salmonicida whole cell in common carp and the best mothod in vaccine administration. Vaccine was produced by inactivated A. salmonicida with adding 1 ppm (v/v) formaldehide and incubated for 24h in room temperature. Ten juvenil of carp (Vaccine was administrated in each 10 fish by injection intraperitoneally (107 cfu/fish), orally (107 cfu/fish), immersion (107 cfu/ml for 30 minute) and control (fish with no vaccination). Booster was conducted 7 days after first vaccination with same dossage and method. Titer antibody was evaluated in three times i.e. before vaccination, 7th days after first vaccination, and 7th days after booster. Water quality such as dissolved oxygen, pH, and water temperature was measured as a supported parameters. Results showed that titer antibodi for all treatment before vaccination was 1/6. However, titer antibody after vaccination and booster increased to 1/58.67 and 1/85.33 for i.p injection, 1/42.67 and 1/64 for oral, 1/24 and 42.67 for immerse, respectively. Whereas, there was no significantly increasing of titer antibody in control that was 1/9.33 and 1/18.67 for vaccination and bosster, respectively. Vaccine adminsitration method by injection i.p. was the best method for obtain the best immunogenicity of vaccine. Water quality parameters along this experiment still in optimum range for common carp living.

Abstract

Penerapan biosekuritas pada budidaya udang vaname (Litopenaeus vannamei) dan hubungannya secara deskriptif dengan infeksi penyakit virus dan parasit dan performa budidaya  dipelajari untuk keberlanjutan budidaya udang di Kabupaten Pesawaran. Penelitian dilakukan dengan kuisioner standar biosekuritas, diagnosis penyakit virus, identifikasi jenis parasit dan performa budidaya udang. Penelitian menggunakan empat desa yang merupakan sentra budidaya udang di Kabupaten Pesawaran antara lain Hanura, Sidodadi, Gebang, Seribu dengan mengambil 16 petak tambak sebagai sampel. Hasil penelitian menunjukkan terdapat modifikasi penyediaan sarana, prasarana dan aplikasi biosekuritas pada empat desa dibandingkan biosekuritas standar. Modifikasi biosekuritas yang buruk di Desa Hanura menyebabkan infeksi penyakit virus dan budidaya udang tidak berlanjut. Modifikasi biosekuritas di Desa Sidodadi, Gebang dan Seribu yang berbeda mempengaruhi performa budidaya udang. Penerapan standar biosekuritas yang konsisten sesuai aturan lokal, nasional dan internasional diperlukan agar keberlanjutan industri udang vaname di Kabupaten Pesawaran dapat dipertahankan.

Abstract

Permasalahan pembesaran lele masamo (Clarias sp.) yang terjadi antara lain yaitu kompetisi untuk mempertahankan ruang gerak, mempertahankan hidup dan  konversi pakan menjadi daging kurang optimal yang  mengakibatkan penurunan dalam pertumbuhan dan penurunan  produksi. Penelitian bertujuan mengetahui efektivitas dasar kolam buatan pada pembesaran lele masamo menggunakan penambahan probiotik dan vitamin C terhadap biomassa akhir, kelangsungan hidup, panjang dan bobot ikan. Penelitian dilakukan menggunakan rancangan acak lengkap (RAL) yang terdiri 3 perlakuan  diantaranya adalah perlakuan pemeliharaan lele masamo tanpa menggunakan dasar kolam buatan, tanpa probiotik dan tanpa penambahan vitamin C   pada pakan (TDPC); pemeliharaan lele masamo tanpa menggunakan dasar kolam buatan, dengan penambahan probiotik pada air kolam dan vitamin C pada pakan (TDKB); pemeliharaan lele masamo dengan menggunakan 2 dasar kolam buatan dan penambahan probiotik pada air kolam dan vitamin C pada  pakan (DVPC). Hasil menunjukkan bahwa perlakuan dasar kolam buatan, penambahan probiotik pada air kolam dan penambahan vitamin C pada pakan (DVPC) pada pembesaran lele masamo super intensif berpengaruh nyata terhadap kelangsungan hidup dengan kelangsungan hidup mencapai 94,67%. Tetapi,  perlakuan dasar kolam buatan, penambahan probiotik pada air kolam dan penambahan vitamin C pada pakan  pada pembesaran lele masamo super intensif tidak  berpengaruh nyata terhadap pertumbuhan,  konversi pakan dan biomassa lele masamo. Penelitian ini juga membuktikan bahwa teknologi dasar kolam buatan efektif untuk meningkatkan produksi sebanyak 10% dari produksi normal. Lebih lanjut, pembesaran lele masamo skala super intensif memerlukan aplikasi probiotik dan vitamin C untuk menjaga imunitas dan kualitas air selama pemeliharaan.
